ios - iOS 7.1.2 RESideMenu 在 +[UIView appearanceWhenContainedInInstancesOfClasses:] 上崩溃：发送到类的无法识别的选择器

Question

我从https://github.com/romaonthego/RESideMenu在我的项目中添加了RESideMenu库。它在8,9 上运行良好，但在7.1.2 上崩溃。iOSiOSiOS

问题是：

+[UIView appearanceWhenContainedInInstancesOfClasses:]: unrecognized selector sent to class 0x3c265a78
Sep 21 14:48:37 iPhone HafiziQuran[476] <Error>: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '+[UIView appearanceWhenContainedInInstancesOfClasses:]: unrecognized selector sent to class 0x3c265a78'

我的实现appdelegate是：

self.dmVC=[[DEMOFirstViewController alloc] init];
self.navigationController = [[UINavigationController alloc] initWithRootViewController:self.dmVC];//[[DEMOFirstViewController alloc] init]

self.leftMenuViewController = [[DEMOLeftMenuViewController alloc] init];
self.rightMenuViewController = [[DEMORightMenuViewController alloc] init];

self.sideMenuViewController = [[RESideMenu alloc] initWithContentViewController:self.navigationController
                                                                leftMenuViewController:self.leftMenuViewController
                                                               rightMenuViewController:self.rightMenuViewController];

self.sideMenuViewController.menuPreferredStatusBarStyle = 1; // UIStatusBarStyleLightContent
self.sideMenuViewController.delegate = self;
self.sideMenuViewController.contentViewShadowColor = [UIColor blackColor];
self.sideMenuViewController.contentViewShadowOffset = CGSizeMake(0, 0);
self.sideMenuViewController.contentViewShadowOpacity = 0.6;
self.sideMenuViewController.contentViewShadowRadius = 12;
self.sideMenuViewController.contentViewShadowEnabled = YES;
self.window.rootViewController = self.sideMenuViewController;
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
